Inspections Before Trouble DiagnosisNCS00024
A/T FLUID CHECK
A/T Fluid Leakage and A/T Fluid Level Check
Inspect for A/T fluid leakage and check the A/T fluid level. Refer to AT- 1 2 , "Checking A/T Fluid" .
A/T Fluid Condition Check
Inspect the A/T fluid condition.
STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the A/
T fluid temperature is 50 to 80°C (122 to 176°F). Inspect the
amount of ATF. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Engine start, apply foot brake, and place selector lever in “D”
position.
5. While holding down the foot brake, gradually press down accel-
erator pedal.
6. Quickly read off the stall speed, then quickly remove your foot
from accelerator pedal.
CAUTION:
Do not hold down accelerator pedal for more than 5 sec-
onds during this test.
7. Move selector lever to “N” position.
Fluid condition Conceivable Cause Required Operation
Varnished (viscous
varnish state)Clutch, brake

T main unit and the vehicle for
malfunctions (wire harnesses,
cooler pipes, etc.)
Milky white or cloudy Water in the fluidReplace the ATF and check for
places where water is getting in.
Large amount of metal
powder mixed inUnusual wear of
sliding parts within
A/TReplace the ATF and check for
improper operation of the A/T.

8. Cool down the ATF.
CAUTION:
Run the engine at idle for at least one minute.
9. Repeat steps 5 through 8 with selector lever in “R” position.
Judgment Stall Test
O: Stall speed within standard value position
H: Stall speed higher than standard value
L: Stall speed lower than standard value
Stall Test Standard Value Position
LINE PRESSURE TEST
Line Pressure Test Port
Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the ATF reaches in range of 50 to 80°C (122 to
176°F), then inspect the amount of ATF and replenish if necessary.
NOTE:
The A/T fluid temperature rises in range of 50 to 80°C (122 to 176°F) during 10 minutes of driving.
